This study discusses, through bibliographic research, the recurrence of naturalization as basis for the medicalization of the female body, as a means of social control through biological reproduction, whereby behavioral standards, social class, ethnic and race differences are rearranged/redefined. Through this process, male patriarchal and class predominance is maintained and the rift of social and gender inequalities grow wider. It is important to identify the role of technological developments and their complexities - which do not allow lower-income classes to take decisions in regard to their own bodies and reproductive health - and schooling, specially through science and physical education classes whereby upper-class predominance is sustained.
